EMBROIDERED SEAT/I.

Application filed une 12, 1913.

To all whom t may concern: y

Be it lmown that I, RUDOLF Lone, a citizen of the United States, and aresident of Jenkintown, Montgomery county, Pennsylvania, have inventedcertain improvements in Embroidered Scams, of which the following is aspecification.

My invention relates to surface ornamentation for fabrics morefamiliarly known as embroidery, which ornamentation may be mechanicallyproduced; and the object of my invention is to produce an improvedcharacter of eyelet embroidery with a stitched edge entirely surroundingan aperture on the one hand, or on the other hand a seam of similarcharacter which may inclose a plain space of the fabric receiving otherornamentation.

These and other features of my invention are more fully describedhereinafter, reference being had to the accompanying drawings formingpart thereof, in which:

Figure l, is a view illustrating a piece of fabric and holder for thesame; such fabric being shown in the course of ornamentation inaccordance with my invention;

Fig. 2, is a perspective view illustrating the manner of effecting theinclosure of the edges of openings formed in such fabric;

Fig. 3, is an enlarged plan view of one form of opening to receive anembroidered seam;

Fig. 4, is an enlarged plan view of another form of opening to receivean embroidered seam;

Fig. 5, is an enlarged view of an embroidered seam effected around anopening such as shown in Fig. 3, and

Fig. 6, is an enlarged plan view of an embroidered seam effected aroundan opening such as shown in Fig. 4.

The main object of my invention is to provide an eyelet for aperturedembroidery. To this end a piece of fabric 1 may be prepared by punchingthe same as at 2; such fabric being then stretched in an ordinarytambour frame, such as 3, and then by means of a sewing machineemploying an oscillating needle, indicated at 4C, with which a suitableshuttle coperates, I form stitches entirely surrounding the openingsformed in the fabric.

In my application for patent filed October 2, 1912, Serial No, 723.572,I have shown slits which, having stitches applied to their Specificationof Letters Patent.

edges, are spread in the manner indicated in the drawings so thatelongated apertures are produced with bound edges. lf a truly circularopening is provided and the stitches are laid by the oscillating needlein the usual manner, the stitches will form an edging of what may betermed buttonhole stitches; all of which are of the same length andradially disposed, and the width of such stitching surrounding the edgeof the aperture will be substantially uniform. llt may be desirable,however, to effect an embroidered eyelet or seam which may be wider andthicker at one portion than'at another, and in order to accomplish thisresult, in accordance with one part of my invention, l may provide holessuch as .indicated in Figs. 3 and 4, in which a portion of the fabric isleft to be inclosed by the seam,

In my application above referred to, a portion of the fabric is inclosedby the seam in the process of forming the same; the operator pulling thefabric as the stitches are being formed so as to widen the same in thecenter.

in the present arrangement in the formation of the substantially roundor eccentric eyelet, which will have a thickened side formed bygradually lengthened stitches, a semicircular aperture 10 is formed, andthen during the sewing operation the portion of the fabric indicated at:c is bound in by the stitches, and the stitches effecting this bindingin are longer than those of the rest of the seam so that the latterforming the eyelet has a thicker portion at one side than at another. Ineffecting this result, the movement of the oscillating needle in layingthe stitches is always the same, but the stitches will vary in length,since a greater portion of the fabric will be inclosed by said stitchesat one point of the eyelet than at another. Where the short stitches aremade, the thread is drawn tightly by the needle after the formation ofeach stitch, and as there is no fabric to be inclosed, such stitches arevery short. As the fabric is inclosed, however, the stitches graduallylengthen.

rFhe same result is accomplished in the production of the elongatedeyelets, as illustrated in Fig. 6, in which the end of the aperture ll,as shown in Fig. 4, is squared instead of being rounded at one end, andthe stitching made catches up the fabric y left between the straightmarginal edging Clt lex;

and the curve which the innei` margin of the stitches must form as theneedle is operated thereon.

In each instance, a portion of the fabric is tucked under the edge ofthe aperture, being completely inclosed by the stitches formed vby theneedle threads, which are locked by the shuttle thread. Such caughtportion of the fabric serves to stuff the .stitched edges of theapertures, and acts further as a stifener for the: same.

If desired, a round hole can be punched,

and then. by placing the saine eccentrically to the normal center of theneedle, the stitches 'laid will catch up more fabric on one side thanthe otherI and stuit' that side, producing the eccentric effect. In theform of embroidery shown in Fig. 5, the stitches are radially disposedwith reference to an imaginary axis eccentric to the outer margin of theeyelet so formed, while in the form shown in Fig. G, the stitches of therounded end of the saine are radial with respect to an axis within theopening.

Claim:

l. As a new article of manufact-ure, an embroidered seam forming aneyelet and composed of stitches. disposed upon a fabric and surroundingand constituting the border of an aperture; said stitches differing inlength throughout their extent whereby an embroidered seam is producedhaving inner and outer margins of different size but substantially thesaine contour; certain of said stitches inclosing a portion of thefabric which serves to stuff said stitches and raise the saine above theplane of the fabric.

2. As a new article of manufacture, an embroidered seam forming aneyelet and composed of'stitches radially disposed upon 40 a fabric andsurrounding and constituting the border of an aperture; said stitchesdiffering in length throughout their extent and formin a substantiallycircular exterior margin with a circular interior inaroin eccentric tothe exteriormargin whereby an embroidered seam is produced having twomargins of substantially the same contour but of different size; certainof the stitches inclosing a portion of the fabric which RUDOLF LOEB.lVitnesses JAMES W.
